Because Windows does not have an equivalent of :func:`time.tzset`, on Windows, :class:`dateutil.tz.tzlocal` instances will always reflect the time zone settings *at the time that the process was started*, meaning changes to the machine's time zone settings during the run of a program on Windows will **not** be reflected by :class:`dateutil.tz.tzlocal`. Because ``tzwinlocal`` reads the registry directly, it is unaffected by this issue. c Cstdtjd}t|t }t|}Wdn1swY|d|_|d|_z+tdj t |jd}t||}t|}|d|_ Wdn1sQwYWn t ycd|_ YnwWdn1snwY|d |d}||d}t j|d |_t j|d |_td |d } | d d \|_|_|_|_| d|_td |d} | d d \|_|_|_|_| d|_|j|j|_||_dS)NZ StandardNameZ DaylightNamez {kn}\{sn})rYZsnr[ZBiasZ StandardBiasZ DaylightBiasr]z=8hZ StandardStartrr Z DaylightStart) rr r rTZLOCALKEYNAMErdr=r>rrcrrKOSErrorrgrhr3r4rerfrPr7r9r;r5rOr8r:r<r6rVrTrM) rrZ tzlocalkeyrjrirDZ_keydictrlrmrkrrrrsP            ztzwinlocal.__init__cCsdS)Nz tzwinlocal()rr0rrrrpBsztzwinlocal.__repr__cCrn)Nztzwinlocal(%s))ror=r0rrr__str__Esztzwinlocal.__str__cCs |jdfS)Nr)rrr0rrrrsIrUztzwinlocal.__reduce__N)r*r+r,r-rrprwrsrrrrrs . rc CsTt||d||}|j||ddd}||dt}|j|kr(|t8}|S)z> dayofweek == 0 means Sunday, whichweek 5 means last instance rr )Zday)rgreplaceZ isoweekdayONEWEEKmonth) rRrzZ dayofweekZhourZminuteZ whichweekfirstZ weekdayoneZwdrrrrNMs  rNcCsi}t|d}d}t|D];}t||\}}}|tjks$|tjkr-|d@r,|d}n|tjkrF|drA|p;t}| |}| d}|||<q|S)z0Convert a registry key's values to a dictionary.rNllz@tzres) rrGrFZ EnumValueZ REG_DWORDZREG_DWORD_LITTLE_ENDIANZREG_SZr%r r)rstrip)keyZdoutsizeZtz_resrBZkey_namevalueZdtyperrrrd[s        rd)r-rgreZ six.movesrZsixrrrr( ImportErrorZ_commonr__all__rhryrrrurrobjectr r.rrrNrdrrrrs2      MM9J
